title: Synthesis of imidazo [4,5-b] pyridine-7-carboxylic acid and some of its derivatives with expected antituberculous activity.
abstract: The title acid 2 and its methyl ester 3, hydrazide 4, hydrazone 5, amide 6, nitrile 7, amidoxime 8 and thioamide 9 have been obtained. As a result of methylation of 2 with diazomethane N-CH3 derivatives of these compounds 10-17 were obtained and their structure was preliminary established as 3-CH3 compounds. Some of the obtained compounds were investigated for their tuberculostatic activity.
